In connection with the construction of the highway on E4 between Strömsnäsbruk and the county border to Skåne in 2004-2006, about 100 000 tonnes of asphalt were recycled by new technologies according to Swedish standards. These asphalt materials came mainly from those parts of the old E4 with adjoining sections of road that were dug out in connection with the construction of the new road. In the northern part of the object, stage 1, the Swedish Road Administration (SRA) had a permission from the environmental authority to recover about 30 000 tonnes of tar contaminated asphalt by cold recycling with foamed bitumen (asphalt foam). In the southern part of the object, stage 2, about 70 000 tonnes of crushed asphalt pavement (asphalt granulate) were recycled without the addition of new binders. In both cases, the reclaimed asphalt was used as base course under the regular asphalt pavement. It replaced the conventional base course of crushed rock with the same thickness, 80 mm or 150 mm.

This report describes tests with recycling of crushed asphalt pavement (asphalt granules) as base course in stage 2. The road has been followed up during 2006-2010. During the construction phase compaction test was performed and the asphalt material was characterized by laboratory tests. The highway was opened to traffic in June 2006. Wearing course was laid in the summer of 2007.
